Abstract

The invention discloses a processing method of household garbage. The processing method comprises the following steps of processing the household garbage through working procedures such as a crushing procedure, a fermenting procedure, a sorting procedure and a classifying comprehensive processing procedure. The processing method disclosed by the invention has the advantages that the urban household garbage is subjected to resource comprehensive processing, the cost is low, the recycling utilization or regeneration of different substances of the garbage is realized, and the purpose that the garbage pollution is thoroughly controlled, and the reduction as well as harmless and resource processing are realized are achieved.

Description

The processing method of one way of life rubbish

Technical field

The present invention relates to garbage treating process, particularly the processing method of one way of life rubbish.

Background technology

The processing method of the current house refuse of China mainly contains three kinds: the one, and sanitary landfill method; The 2nd, garbage compost method; The 3rd, waste incineration method.These processing methods have his own strong points, but all have some problem and shortage, are restricting the development of China's garbage disposal cause.

Sanitary landfills is that rubbish is inserted in ready hole and covered compacting, makes it that biology, physics, chemical change occur, and decomposing organic matter, reaches minimizing and innoxious object.Sanitary landfill method, as the Landfill of house refuse tradition and final disposal mode, accounts for very large proportion in China.The method is simple, invests littlely, can process the rubbish of all kinds.Also exist simultaneously landed property large, can not comprehensively reclaim valuable material and the energy, secondary pollution is more serious, diffusate intractability is large or processing cost is very high, larger to underground water and ambient influnence in the neighbourhood.

Compost treatment is that Urban Garbage Treatment in China use is also that commitment is used maximum modes the earliest.Compost is the organic matter making in rubbish, ight soil, under microbial action, carries out biochemical reaction, organic matter, oxygen and bacterial interactions, separate out carbon dioxide, water and heat, finally form a kind of material of similar humus soil, as fertilizer or improvement soil.Composting technology can be carried out the utilization of resources to the part component in rubbish, and after compost treatment, house refuse becomes health, tasteless humus, and organic matter is become to organic fertilizer or soil conditioner, and the resource that realizes discarded object transforms.Also there is the shortcoming that the compost cycle is long, floor space is large, nutrient content is low in compost treatment simultaneously, long-term use easily causes soil compaction and groundwater quality to degenerate, and technical matters is complicated, if sorting is not thorough, with composting, carry out compost, organic matter fermentation factor owes scientific, and many harmful substances can enter soil with compost and cause secondary pollution.

Burning is a kind of technology of garbage disposal of destroying garbage utilization heat energy, is that rubbish is placed in to high temperature furnace, and wherein combustible component is fully oxidized, and the heat of generation is for generating and heating, and essence is exactly the chemical reaction of the elements such as carbon, hydrogen, sulphur and oxygen.Simultaneously there are many unfavorable factors in burning disposal, and as disposable construction investment with operating cost is high, operational management difficulty is large, atmosphere pollution is serious, and current stomach Qi treatment technology has much room for improvement.

Summary of the invention

The object of the invention is to overcome limitation and the defect of various waste disposal methods in prior art, provide that a kind of construction investment is few, operating cost is low, simple to operate, treatment effect good, resource circulation utilization degree is high, can extensively be suitable for the garbage disposal of different scales, different rubbish qualities, and the waste disposal method of non-secondary pollution.

The present invention is achieved through the following technical solutions: the processing method of one way of life rubbish, and its step is divided into:

1) rubbish is at normal temperatures and pressures through broken, fermentation; Then,

2) rubbish is carried out to three major types sorting, a class is the material of recoverable, as waste paper, old metal, cullet etc.; The 2nd, the organic matters such as kitchen excess; The 3rd, the inorganic matters such as sandstone, dregs;

3) again the rubbish sub-electing is carried out to integrated treatment, the organic matter sub-electing is made to efficient composite organic fertilizer, the material of the reproducible utilizations such as waste paper, old metal, cullet is reclaimed respectively, and the inorganic matters such as remaining sandstone, dregs are used for doing construction material or brickmaking;

4), to the rubbish without recovery value after integrated treatment, carry out harmless treatment.

In such scheme, it is deep processing composting that organic matter is made composite fertilizer, comprises following operation: sterilizing, secondary fermentation, adds nutrient, is uniformly mixed granulation, oven dry, cooling, particle screening, finished product packing.

Beneficial effect of the present invention is:

The present invention carries out comprehensive resource processing to domestic waste, not only expense is lower, and all kinds of materials of rubbish have all been realized to utilization or the regeneration of resource, and reached thorough improvement refuse pollution, realized minimizing, innoxious and recycling treatment object.

The specific embodiment

Below the preferred embodiments of the present invention are described.Should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.

The processing method of one way of life rubbish, its step is divided into:

1) rubbish is at normal temperatures and pressures through broken, fermentation; Then,

2) rubbish is carried out to three major types sorting, a class is the material of recoverable, as waste paper, old metal, cullet etc.; The 2nd, the organic matters such as kitchen excess; The 3rd, the inorganic matters such as sandstone, dregs;

3) again the rubbish sub-electing is carried out to integrated treatment, the organic matter sub-electing is made to efficient composite organic fertilizer, the material of the reproducible utilizations such as waste paper, old metal, cullet is reclaimed respectively, and the inorganic matters such as remaining sandstone, dregs are used for doing construction material or brickmaking;

4), to the rubbish without recovery value after integrated treatment, carry out harmless treatment.

As preferred embodiment, it is deep processing composting that described organic matter is made composite fertilizer, comprises following operation: sterilizing, secondary fermentation, adds nutrient, is uniformly mixed granulation, oven dry, cooling, particle screening, finished product packing.
